We're told the Orlando PD was contacted around 3 PM on Sunday after Alberto -- real name Jose Rodriguez -- allegedly roughed up a female companion.

We spoke with witnesses who tell us Alberto and the woman were arguing in the terminal and when things escalated, cops were called.

As one witness put it, "There was an altercation."

Our law enforcement sources tell us Alberto has NOT been arrested and no charges have been filed -- investigators are still gathering information.

Cops would not confirm the name of the alleged victim. However, Alberto has been in a real-life relationship with WWE superstar Paige for a while and witnesses say she was at the airport with Alberto that day.

We reached out to Alberto's camp for comment -- so far, no word back.

Alberto is the current Impact Wrestling heavyweight champion. He was also a WWE heavyweight champ but broke off from the organization in 2016.
